Avoiding two consecutive classes in the same class

[Raja Kashif Ilyas]

Greetings FET forum!

I am having an issue that during some generations of timetable, a teacher appears to have consecutive classes (of different subjects but same teacher and same class) which doesn't seem quite right because it is exhaustive for the teacher as well as students. So I want to know if there are any constraints or tips on how to avoid consecutive classes of the same teacher in any class?

Hello!

I think teachers or students activity tag max hours continuously.

hmm.. I must admit that i like those consecutive hours and doesn't think they are exhaustive. Maybe ask every body before adding such a constraint. For example i want those consecutive hours and "complain" if they are not consecutive.

Why?
a) The students and the teachers doesn't need to swap the room (if there is no special room for a subject needed)
b) sometimes i didn't finish the hour in time, so i just continue a few minutes (or sometimes the whole hour) with the "old" subject. Of course in return i do it oposite the next week.
c) sometimes i need 2 hours to write a math test. But if i have only 1 hour per day math, then i always need to swap with an other teacher. That is sometimes difficult to do. But if i have such continues hours, then i can do it myself without careing about other teachers (and so also without affecting other students too!)
...
So overall i like those hours.
